Description

Technical Field

[0001] This utility model belongs to the field of marine downlight technology, specifically relating to a marine downlight with fire-resistant properties. Background Technology

[0002] Recessed lights are popular because they can be embedded in the ceiling, maintaining the overall unity and perfection of the building's decoration. They are widely used in indoor lighting such as homes, offices, and shopping malls. Recessed lights are also commonly used for lighting in ship cabins and restrooms.

[0003] Currently, in existing technologies, downlights used in ship cabins or toilets are generally of an integral structure. If the lamp body inside the downlight is damaged, the entire downlight needs to be replaced, resulting in excessively high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a marine downlight with fire-resistant properties to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine downlight with fire-resistant properties, comprising a lamp barrel, a lamp body, a heat dissipation rear shell, and a connecting mechanism. The lamp barrel has a mounting opening at its rear end for mounting the lamp body, which is inserted into the mounting opening. An annular slot is provided around the mounting opening at the rear end of the lamp barrel. One end of the heat dissipation rear shell is inserted into the annular slot. A limiting ring is provided on the inner sidewall of the heat dissipation rear shell, abutting against the rear end of the lamp body. A plurality of heat dissipation rods are fixedly connected to the heat dissipation rear shell, and a heat-conducting sheet is fixedly connected to one end of each heat dissipation rod, abutting against the rear end of the lamp body.

[0006] The connecting mechanism includes a connecting groove formed around the lamp body and the heat dissipation back cover. An annular sliding groove is formed at the rear end of the lamp tube. A sliding ring is slidably connected in the annular sliding groove. A spring is abutted against the bottom of the sliding ring. Multiple annularly distributed guide posts are fixedly connected inside the sliding ring. Connecting blocks are slidably connected to the surface of the guide posts.

[0007] In a preferred embodiment, a lens is fixedly connected to the opening at the lower end of the lamp tube, and a first fireproof ring is provided between the lens and the inner wall of the lamp tube.

[0008] In a preferred embodiment, a reflector cup is fixedly connected to the inner wall of the lamp tube, and fireproof cotton is provided between the reflector cup and the inner wall of the lamp tube.

[0009] In a preferred embodiment, the inner bottom wall of the annular slot is provided with a second fireproof ring.

[0010] In a preferred embodiment, a fire-retardant coating is provided on the outer surface of the lamp tube.

[0011] In a preferred embodiment, the end of the connecting block away from the slip ring is provided with an angle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This fire-resistant marine downlight, through the setting of the first fireproof ring, can play a fireproof role in the gap between the lens and the lamp tube; through the setting of the fireproof cotton, it can play a fireproof role inside the lamp tube; through the setting of the second fireproof ring, it can play a fireproof role in the gap between the heat dissipation shell and the lamp tube; through the setting of the fireproof coating, it can improve the fireproof performance of the lamp tube surface.

[0014] This fire-resistant marine downlight, through its heat dissipation back cover and connecting mechanism, allows for easy installation. The lamp body is inserted into the lamp tube through the mounting port at the rear end, followed by the heat dissipation back cover into the annular slot at the rear end of the lamp tube. A limiting ring abuts against the lamp body, restricting its movement. A heat-conducting plate contacts the lamp body, transferring heat generated within. The heat is then dissipated through a heat dissipation rod. Once the heat dissipation back cover is inserted into the annular slot at the rear end of the lamp tube, a spring applies elastic force to a slip ring, causing it to slide upwards. A guide post inside the slip ring drives a connecting block to slide, inserting it into a connecting groove, thus connecting the lamp body and the heat dissipation back cover. In case of lamp body damage, the heat dissipation back cover can be opened, and the lamp body removed and replaced independently, reducing future maintenance costs. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a fire-resistant marine downlight, including a lamp barrel 1, a lamp body 2, a heat dissipation rear shell 3, and a connecting mechanism 4. A mounting port 11 for mounting the lamp body 2 is provided at the center of the rear end of the lamp barrel 1. The lamp body 2 is inserted into the mounting port 11. An annular slot 12 is provided around the mounting port 11 at the rear end of the lamp barrel 1. One end of the heat dissipation rear shell 3 is inserted into the annular slot 12. A limiting ring 31 is provided on the inner side wall of the heat dissipation rear shell 3, and the limiting ring 31 abuts against the rear end of the lamp body 2. Several [unclear - possibly referring to a specific type of device] are fixedly connected to the heat dissipation rear shell 3. The heat sink 32 has a heat-conducting plate 33 fixedly connected to one end. The heat-conducting plate 33 abuts against the rear end of the lamp body 2. With the setting of the heat dissipation shell 3, when installing the lamp body 2, the lamp body 2 is inserted into the lamp tube 1 from the mounting port 11 at the rear end of the lamp tube 1, and then the heat dissipation shell 3 is inserted into the annular slot 12 at the rear end of the lamp tube 1, so that the limiting ring 31 abuts against the lamp body 2 to limit the lamp body 2. The heat-conducting plate 33 contacts the lamp body 2 and transfers the heat generated by the lamp body 2. The heat is discharged through the heat sink 32 to dissipate heat from the lamp body 2.

[0022] Furthermore, a lens 13 is fixedly connected to the opening at the lower end of the lamp tube 1, and a first fireproof ring 14 is provided between the lens 13 and the inner wall of the lamp tube 1. The first fireproof ring 14 can play a fireproof role in the gap between the lens 13 and the lamp tube 1.

[0023] Furthermore, a reflector cup 15 is fixedly connected to the inner wall of the lamp tube 1, and a fireproof cotton 16 is provided between the reflector cup 15 and the inner wall of the lamp tube 1. The fireproof cotton 16 can play a fireproof role inside the lamp tube 1.

[0024] Furthermore, a second fireproof ring 17 is provided on the inner bottom wall of the annular slot 12. The second fireproof ring 17 can play a fireproof role in the gap between the heat dissipation shell 3 and the lamp tube 1.

[0025] Furthermore, a fire-retardant coating 18 is provided on the outer surface of the lamp tube 1, which improves the fire resistance of the lamp tube 1 surface.

[0026] Specifically, the connecting mechanism 4 includes a connecting groove 41 formed around the lamp body 2 and the heat dissipation rear shell 3. An annular sliding groove 42 is formed at the rear end of the lamp tube 1. A sliding ring 43 is slidably connected within the annular sliding groove 42. A spring 44 abuts against the bottom of the sliding ring 43. Multiple annularly distributed guide posts 45 are fixedly connected inside the sliding ring 43. A connecting block 46 is slidably connected to the surface of each guide post 45. The end of the connecting block 46 away from the sliding ring 43 is angled. An inclined guide hole is formed inside the connecting block 46. The post 45 passes through the guide hole. With the connection mechanism 4, when the heat dissipation shell 3 is inserted into the annular slot 12 at the rear end of the lamp tube 1, the spring 44 can apply elastic force to the slip ring 43, causing the slip ring 43 to slide upward. The guide post 45 inside the slip ring 43 drives the connecting block 46 to slide, so that the connecting block 46 is inserted into the connecting slot 41, thereby connecting the lamp body 2 and the heat dissipation shell 3. After the lamp body 2 is damaged, the heat dissipation shell 3 can be opened, and the lamp body 2 can be taken out and replaced independently, reducing the maintenance cost in the later stage.

[0027] The working principle and usage process of this utility model are as follows: First, when installing the lamp body 2, insert the lamp body 2 into the lamp tube 1 through the mounting port 11 at the rear end of the lamp tube 1. Then, insert the heat dissipation shell 3 into the annular slot 12 at the rear end of the lamp tube 1, so that the limiting ring 31 abuts against the lamp body 2 to limit the lamp body 2. The heat conducting sheet 33 contacts the lamp body 2 and transfers the heat generated by the lamp body 2. The heat is discharged through the heat dissipation rod 32 to dissipate heat from the lamp body 2. After the heat dissipation shell 3 is inserted into the annular slot 12 at the rear end of the lamp tube 1, the spring 44 can be used to apply elastic force to the slip ring 43, causing the slip ring 43 to slide upward. Through the internal conductive ring 43, the heat is dissipated. The column 45 drives the connecting block 46 to slide, so that the connecting block 46 is inserted into the connecting groove 41, thereby connecting the lamp body 2 and the heat dissipation shell 3. If the lamp body 2 is damaged, the heat dissipation shell 3 can be opened and the lamp body 2 can be taken out and replaced independently. The first fireproof ring 14 can play a fireproof role in the gap between the lens 13 and the lamp tube 1. The fireproof cotton 16 can play a fireproof role inside the lamp tube 1. The second fireproof ring 17 can play a fireproof role in the gap between the heat dissipation shell 3 and the lamp tube 1. The fireproof coating 18 can improve the fireproof performance of the surface of the lamp tube 1.
